Abstract

The invention provides high-damage-threshold fluoride phosphate laser glass as a material for preparing an ultraviolet-transmittance window, and a preparation method of the high-damage-threshold fluoride phosphate laser glass. The preparation method comprises the steps of adopting an alkali metal oxide, an alkaline earth metal oxide, alumina, zinc oxide and phosphoric pentoxide as main raw materials, adding a small amount of rare earth fluoride, molding and preparing glass pressing blanks based on the drip injection method after the treatments of high-temperature melting, clarification and homogenizing, and finally obtaining the high-damage-threshold fluoride phosphate laser glass material through the annealing treatment. The fused quartz material can be replaced by the above glass material for preparing lenses, plane windows, prisms and other optical components applied to high-energy and high-power laser systems. In this way, the laser-induced damage problems of ultraviolet optical components made of the fused quartz material in existing high-energy and high-power laser systems can be solved. The load output capability of a laser is further improved. Therefore, the above material can be used for preparing the ultraviolet-transmittance optical components of high-power lasers for laser-driven inertial confinement fusion experiments.
